Identify this coastal landform. Join us today, Society membership is open to anyone with a passion for geography, Royal Geographical Society As sand dunes become colonised with vegetation roots stabilise the sand and hold it together. At the turn, longshore drift continues in the original direction, but its energy is dispersed, lost as the wave refracts and the current spreads, leading to deposition on the sea bed.
